For our ongoing project we are using QT113H-D.We made one PCB in that
we have provided 3 rounds of copper strip with 80 mil as a
electrode . And also X76 Series (0.1 uF)capacitor across SNS1 and SNS2
pins to increase the sensitivity. I want to increase the sensitivity
with this set up, now i am able to achieve a sensitivity of about 4
Inches . What should i do in this setup to increase the sensitivity to
around 12 inches.Please help me regarding this issue.
